So what would have happened is krogoth was branched and then at some
later time a commit was applied to master which added the
libvmi_git.bb recipe. So start by using git to identify this commit,
you can do this while on the krogoth branch still
ie.: git log master -- ./recipes-extended/libvmi/libvmi_git.bb
This will identify commit e2ab59ec3e4b547da635cda725090d42126dcfd2 as
the commit which brought in the libvmi_git.bb recipe, so cherry-pick
ie: git cherry-pick e2ab59ec3e4b547da635cda725090d42126dcfd2
Now attempt to build it 'bitbake libvmi', as you have indicated this
most likely fail as libvirt will require libxl. DO NOT port the
libvirt recipe from master back to krogoth, libvirt has been around
for ages in meta-virtualization and libvmi does not have a version
dependency on libvirt. Instead when you inspect the libvirt recipe
already present on the krogoth branch you will see that libxl is a
dependency we can control, we need to ensure we have a suitable
PACKAGECONFIG for libvirt AND that "xen" is not set in the
DISTRO_FEATURES. By default neither of these are set so without having
access to your build I don't know where you are setting either of
these, you will have to use bitbake -e libvmi or similar to find out
where your build is setting either of these and mitigate against this.
Try the above and follow up and we can then move on with any other
bits. It is important that you can prep the backport as you have the
krogoth build ready to go along with a usecase to test the backport,
something Bruce will not have.
